Description

Surgical Suture Holder

Technical field

The utility model relates to an auxiliary medical device clinically used for surgical incision suturing, in particular to a surgical suture fixer.

Background technique

During extracorporeal circulation surgery in cardiothoracic surgery, many surgical sutures are often encountered, which not only easily hinders the operator's vision, but also brings certain difficulties to the hand-washing nurses in managing the sutures. The existing method for fixing surgical sutures is to clamp the ends of the sutures by leather tube clamps or mosquito-type vascular clamps to fix the surgical sutures. However, there are several defects in this method of managing sutures: one, the use of blood vessel clamps to clamp the sutures will more or less cause damage to the sutures to a certain extent; The weight of the pipe clamp itself causes a certain degree of pulling, causing unnecessary tissue or blood vessel damage; third, when there are many surgical sutures, it is not conducive to the identification and knotting of paired sutures. There is also no literature report on a special surgical suture fixation device at present.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned deficiencies in the prior art, to provide a method that can effectively avoid damage to tissues, blood vessels or sutures, and can conveniently fix, distinguish and tie the sutures. and inventory of surgical suture retainers.

In order to achieve the above purpose, the utility model is a surgical suture fixer designed in combination with the operation characteristics of surgical sutures in countless clinical operations. Holes for securing the curved bottom plate to the surgical dressing. An arc-shaped groove corresponding to its length is arranged on the top of the arc-shaped bottom plate, and an elastic silicone strip whose upper half is exposed outside is fixed in the arc-shaped groove. Y-shaped slit for embedding surgical sutures in the Y-shaped slit. Further, a scale mark corresponding to the position of the Y-shaped slit is provided on the upper surface of the arc-shaped bottom plate, so as to accurately indicate the position of the Y-shaped slit to the operator.

The utility model has the advantages that the designed arc-shaped bottom plate has a light structure and is fixed on the surgical dressing during use, which can effectively reduce the pulling of the patient's tissue and blood vessels, and can also save the manpower of medical operators. The designed Y-shaped slit on the elastic silicone strip not only facilitates the doctor to quickly and accurately find the Y-shaped opening, but also securely fixes the surgical suture in the Y-shaped straight slit. Moreover, the designed elastic silicone strip is arranged in an arc relative to the wound suture, and its arc-shaped centripetal structure is conducive to the operator to arrange each pair of sutures in the Y-shaped gap in an orderly manner, which is not easy to confuse, and is convenient for paired sutures. The thread is knotted. At the same time, when calculating the number of suture needles, it is not necessary to take off one by one and count them, and only need to take off the fixer itself together with the cut surgical sutures and count the number. It has been proved by clinical practice that this fixer is especially suitable for extracorporeal circulation operations, such as aortic valve replacement, etc., and can replace the traditional leather tube clamp clamping wire fixing method, and has high practical value.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The surgical suture fixer shown in the figure has a curved bottom plate 3, which is made of PVC material. This light PVC material has the characteristics of smooth surface, light weight, waterproof and moisture-proof, and easy to clean. , and can be sterilized in a low-temperature sterilizer for use. The chord length of the arc-shaped bottom plate 3 is 22 cm, the plate thickness is 0.9 cm, and the corresponding central angle thereof is generally 100-140°, so as to facilitate fixing surgical sutures from different directions. The central angle corresponding to the arc-shaped bottom plate 3 is preferably 120°. In this way, three fixators can be used in one operation. The three fixators are connected to form a ring, which is very suitable for aortic valve replacement in three directions. Surgical application of suturing the aortic annulus.

An arc-shaped groove 7 corresponding to its length is provided on the upper surface of the arc-shaped bottom plate 3 , and the cross-section of the arc-shaped groove 7 is V-shaped. The arc-shaped groove 7 is embedded with an elastic silicone strip 4 whose upper part is exposed outside. The cross section of the elastic silicone strip 4 is circular and its diameter is 1 cm. The elastic silicone strip 4 with a circular section is embedded in the arc-shaped groove 7 with a V-shaped section, which is very easy to locate. The two ends of the elastic silicone strip 4 are provided with a fixed collar 2, and the fixed collar 2 adopts a commercially available "easy-to-pull" plastic collar, which is set on the arc-shaped bottom plate 3 and the elastic silicone strip 4, and shrinks and locks. The positions of the two can be fixed. The fixed collar 2 can also be disassembled at any time to facilitate the cleaning and disinfection of each part. Of course, other methods can also be used to fix the arc-shaped bottom plate 3 and the elastic silicone strip 4 .

There is a Y-shaped gap 5 every 1 cm on the top of the elastic silicone strip 4, and a black scale mark 6 indicating the position of the Y-shaped gap 5 is correspondingly engraved on the top of the arc-shaped bottom plate 3, so that the doctor can find the desired location intuitively, accurately and quickly. The position of the Y-shaped slit 5 that needs to be embedded, and the surgical sutures are firmly embedded in it. The two ends of the arc-shaped base plate 3 are provided with base plate positioning holes 1, and the base plate positioning holes 1 adopt conventional circular holes. Use small cloth towel pliers to pass through the circular base plate positioning holes 1, and clamp surgical dressings such as abdominal quilts or chest quilts. class, the arc base plate 3 can be fixed. In order to further ensure the stability of the arc-shaped base plate 3, an adhesive layer that is bonded and matched with the surgical dressing can also be set on the bottom surface of the arc-shaped base plate 3, so that the arc-shaped base plate 3 can be firmly fixed on the surgical dressing even without cloth towel pliers. It can effectively prevent the patient's tissue and blood vessel damage caused by its moving and pulling.

The operation method of this surgical suture fixer is as follows: clean it, seal it after drying, put it into a STERRAD 100S hydrogen peroxide plasma low-temperature sterilization pot (manufactured by Johnson & Johnson, USA) and sterilize it for later use. When used in an operation, the surgical suture fixer can be positioned by clamping the dressing with a small cloth towel clamp at the positioning hole 1 of the circular bottom plate. When fixing the surgical suture, it is only necessary to place the end of the suture in the Y-shaped gap of the elastic silicone strip 4.

Experiments have shown that when various types of SURGIPRO vascular sutures such as 2-0, 3-0, and 4-0 or 2-0 TICRON valve replacement sutures are repeatedly fixed on the surgical suture fixer, the sutures can be firmly fixed. Clamp without damaging the appearance and tension of the suture. It has been clinically used in 30 cases of cardiopulmonary bypass surgery, all of which have received good results.
